The address order is reversed and misspelled. It should be Setagaya-ku, Funabashi 5-10-55. The postal code should be 7 numbers, probably 156-0055.
The phone number is too short. it should be two digit city code (03) then 8 digits.
These things probably changed in the couple of decades since you lost contact with her.
Also, if she is still around and still at/near that address, putting this information on a public forum would be an awful breach of privacy, so probably best if the mods delete the phone number, even if it is out of date and does not work.
